It accepts 22 AWG wire and terminates via insulation displacement, so no crimp tool is needed for the wire — just a simple IDC press. The 0.156\" pitch is the spacing between contact centers — it determines the board footprint and the ribbon cable pitch. At 5 positions, this receptacle matches a 5-circuit BOM line exactly. ## How It Compares: MTA-156 vs MTA-100 The MTA-156 series uses a 0.156\" (3.96mm) pitch, while the MTA-100 series uses a 0.100\" (2.54mm) pitch. The wider pitch of the MTA-156 allows for higher current capacity per contact and easier routing for larger wire gauges like 22 AWG. For a 5-position connector, the MTA-156 occupies more board space than an equivalent MTA-100 part, but the trade-off is a more robust connection for power or signal lines where voltage drop matters.","metaTitle":"TE MTA-156 3-643819-5, 5-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 3-643819-5 receptacle, 5 positions, 0.156\" pitch, IDC termination, 22 AWG, tin contacts, locking ramp.
